This would be another case of Trump trying to destroy government from the inside. Myers’s company AccuWeather tried to quash free forecasts: one of the most useful and lifesaving services of the federal government.

Fuck this guy and fuck Trump for nominating him.

As extreme weather conditions and natural disasters lay waste to Northern California and Puerto Rico, Donald Trump is poised to hand over control of the National Oceanic and Atmospheric Administration—the government organization that focuses on weather and climate research—to a known opponent of the agency. Barry Myers, the C.E.O. of for-profit weather forecasting service AccuWeather, has supported measures that would limit how much information the National Weather Service can publicly release, so private companies like his can use N.W.S. data to sell their own products to consumers.

A test of the U.S. National Weather Service’s system to warn Americans about tsunamis appeared to go awry this morning, as residents in states like New York erroneously received alerts that the east coast might be in harm’s way.

At about 8:30 am ET, NWS officials said it sought to complete a monthly test of its tsunami warning system — with an alert that had the word “test” in its message — yet “some users received this test message as an actual tsunami warning.”

Last Wednesday morning we got a rather significant snowfall here in Raleigh that kept us out of work and school for the rest of the week. For a while there, it looked as if the heaviest snow would be directly over Raleigh but the fictitious “Raleigh weather dome” (said by equally-fictitious blogger William Needham Findley IV to be controlled by former Raleigh city council member Bonner Gaylord) kept the heaviest snow to the west of us. When it stopped snowing at our home in East Raleigh I had measured 4.75″.

I worked from home Wednesday through Friday (ah, the joy of being a knowledge worker) but did enjoy how beautiful the snow looked on the trees. It was a clumping sort of snow that wound up sticking very well to branches but causing few issues with broken limbs. I also caught up on some technical projects I’d been meaning to get done. It was a nice winter event, though when the streets had cleared I was quite ready to go for a bike ride!

Last Christmas (2016), I got an AcuRite weather station from Costco as a gift to replace my falling-apart Oregon Scientific station. It’s a decent little setup, with wireless transmission from a multi-sensor box outside to the panel inside. For the longest time my biggest complaint was its need to use Windows software to archive its data.

Then early last year I hooked up the open source weather software weewx to my station. Weewx creates a nice (if simple) graph of weather data (as seen at https://www.markturner.net/wx) and also kicks the data over to my MySQL database so I can save and query those stats. Last month I was able to create a fancy Grafana dashboard that dynamically displays that data in a beautiful format. Now I had taken a $75 weather station and made it much more useful!Continue reading →

It’s sad to read of the devastation to the El Yunque rainforest. It is a national treasure.

LUQUILLO, P.R. — When you looked up, you could once see nothing but the lush, emerald canopy of tabonuco and sierra palm trees covering El Yunque National Forest.

That was before Hurricane Maria obliterated the only tropical rain forest in the United States forest system. Left behind was a scene so bare that on a recent visit, it was possible to see the concrete skyline of San Juan about 30 miles west — a previously unimaginable sight.

El Yunque, pronounced Jun-kay, has been an enormous source of pride in Puerto Rico and one of the main drivers of the island’s tourism industry. The 28,000-acre forest on the eastern part of the island has over 240 species of trees; 23 of those are found nowhere else. Over 50 bird species live among the forest’s crags and waterfalls.

But sunlight now reaches cavities of the forest that have not felt a ray of light in decades, bringing with it a scorching heat.“Hurricane Maria was like a shock to the system,” said Grizelle González, a project leader at the International Institute of Tropical Forestry, part of United States Department of Agriculture. “The whole forest is completely defoliated.”

The Weather Channel also produced a great primer on hurricane “spaghetti models” and what they show and (more importantly) leave out.

There’s a delicious-sounding term that’s about to make its way back into the weather forecasting lexicon as hurricane season ramps up, but it has nothing to do with food.Spaghetti weather models, also known as spaghetti plots, are a simplistic way of conveying a lot of tropical information quickly, but there can also be downfalls to relying on these plots.

1. Spaghetti Plots Do Not Portray Any Impacts

Although most models show possible impacts, to present many models succinctly on a single chart, meteorologists generally produce spaghetti plots that usually only show the “where” and a loose representation of “when” for tropical systems.

To get to this level of brevity, meteorologists must only focus on the center point of a tropical system, which may or may not be accurate. We’ll get to more on that limitation later, but for now, let’s focus on the lack of impacts.

Here’s a good explanation for why one shouldn’t panic about a hurricane that’s a week away from approaching. Pay attention, yes, but there’s no need for panic.

Hurricane Irma will be a formidable hurricane for days to come in the Atlantic Basin, but its future impact in the U.S. remains unknown.Given the record-setting, catastrophic flooding, storm surge and wind damage from Hurricane Harvey, it’s understandable why Irma is making U.S. East Coast and Gulf Coast residents unnerved.

You may wonder why we can’t yet nail down anything specific on Irma’s future potential impact in the U.S. Wouldn’t that help people prepare?

First, we’ll explore why that is. Then we’ll go over some atmospheric patterns typically in place that increase East Coast hurricane risk.
